Using search-operator "OR"

Topic summary

A user is asking how to implement the “OR” search operator in their store’s search functionality. They note that “AND” is currently the default operator and observe that search terms in the URL are separated by “+” symbols.

Another participant clarifies that the “+” character in search URLs (e.g., /search?q=blue+shirt) represents a space character in URL encoding, not a boolean “AND” operator.

The original question about implementing “OR” search functionality remains unanswered. No solution or implementation details have been provided yet.

Hello everyone,
I would like to know how to use the search-operator “OR”. “AND” is set by default in the store. Here it is also the case that a “+” is inserted between the search terms in the URL. What would that look like for “OR”. what does it say in the URL? thank you in advance for your help.
Best regards
Manuel

The “+” inserted between the search terms (e.g. /search?q=blue+shirt) represents a space, not a boolean operator.
